</div>Yes, this is a good choice to reduce caller's overhead. My only concern is, if for some special reason, some plugin failed to be loaded in production environment, it will be difficult to debug since there will be no stacktrace in the log, but possibly it's acceptable.<br>

Also I think we can add a DEBUG information on the ceilometer/extension_manager.py, ActivatedExtensionManager(), to print all plug-ins loaded successfully, to be more user friendly. Any idea?<br></blockquote><div><br></div>
<div>Stevedore is already logging the plugins it finds. <a href="https://github.com/dreamhost/stevedore/blob/master/stevedore/extension.py#L62">https://github.com/dreamhost/stevedore/blob/master/stevedore/extension.py#L62</a></div>
